The Apayao derive their name from their traditional orientation along the Abalug (Apayao) and Matalag river systems in the northern end of the Cordillera range in Kalinga-Apayao Province. They live in well-built multiple family houses clustered together in small, permanent, kin-based villages. Large kinship groups are led by a mengal who has distinguished himself economically as well as demonstrating other leadership skills. Propitious events are commemorated in a feast called the sayam, in which prestigious males compete at boasting around a ritual stone, while specialized female attendants communicate with the spiritual world.
